Abstract

A double-blind comparison of josamycin propionate granule for oral suspension (JM-P) and that of erythromycin ethylsuccinate (ES-EM) was performed on their efficacy and safety in the treatment of scarlet fever inpatients, and the following results were obtained.<BR>1. A total of 159 patients was randomly assigned to two groups of almost equal size: 79 cases to JM-P and 80 to ES-EM groups. Among them, 8 cases medicated with JM-P (10%) and 11 with ES-EM (14%) were removed from analysis because of not filling prerequisites. Medication was 30 to 40 mg (potency) /kg per day for 7 days.<BR>2. No item of background factors was significantly different (P> 0.05).<BR>3. Global efficacy data showed no significant difference between the two groups (P> 0.05). The rate of improvement (excellent plus moderate) was 70% with JM-P and 58% with ES-EM. The rate would become 64% with JM-P (50 out of 78 cases) and 53% with ES-EM (40 out of 76), if 14 among 19 cases removed were taken into account, in which medication was earlier terminated by change to other drugs.<BR>4. The rate of disappearance of pharyngeal streptococci before the 3rd day was 40% with JM-P (23 out of 57 cases) and 39% with ES-EM (19 out of 49), showing no significant difference between them (P>0.05).<BR>The rate of detection of pharyngeal cocci after termination of drug administration was not significantly different between the groups (P>0.05).<BR>5. The rate of defervescence was not significantly different between the two groups (P>0.05). Days for disappearance of eruption and of pharyngeal reddening suggested a trend favorable to JM-P.<BR>6. Global evaluation was shown significantly correlated with the efficacy criteria selected: days for disappearance of pharyngeal streptococci, days for defervescence, days for disappearance of eruption and days for disappearance of pharyngeal reddening in the order cited, except for a nonsignificant correlation between global evaluation and days for disappearance of pharyngeal reddening in the ES-EM group.<BR>7. Changes in ASLO and CRP values before and after medication were similar in both groups. However a slight trend favorable to JM-P was observed.<BR>8. A case medicated with JM-P showed definite rise in SGOT and SGPT values, which did not reveal any clear correlation with medication. As to side effects, a case was encountered who complained a slight abdominal pain during medication of ES-EM.
